SEAT.

Application filed May 26,

To all whom it may concern Be it known that'I, JoHN H. Sroors, a

citizen of the United States, residing at 1,319,976, granted to me October 28,- 1919,

and intended more particularly for use in locomotive cabs. The present invention has special reference to the prop or supporting leg for the free end of the seat and has for its object the provision of a construction which will permit a prop to be readily adjusted to the normal height desired for the seat and which will also accommodate the vibrations of the seat when in use while preventing separation of the parts. The invention also has for its object the provision of means for varying the tension of the spring whereby the free end of the seat is normally supported in a raised position. The invention is illustrated in the accompanying drawings and will be hereinafter fully set forth.

In the drawings V Figure 1 is a side elevation of my improved seat; I

Fig. 2 is an end elevation of the same;

Fig. 3 is an enlarged detail sectional elevation of the prop or adjustable supporting leg for the free end of the seat.

Spaced tubular hangers 1 are secured to a fixed support 2 which may be the side of the locomotive cab, and a seat-carrying rod 3 is constructed at its ends to rest upon double springs or cushioning members 4 housed within the said hangers, spacer disks, indicated at 5, being placed in the bottoms of the hangers to adjust the seat-carrying rod to any desired normal height. The seat 6 has secured to its under side, at its ends, cleats 7 which are provided at their inner ends with hooks 8 adapted to engage around the seat-carrying rod 3 whereby the seat will be pivotally mounted upon the said rod, and spacing collars 9 are provided upon the rod to be disposed at any desired points thereof so that the seat may be shifted along the rod as the user may prefer.

I also secure to the under side of the seat, at the transverse center thereof, a cleat 10 provided with an eye 11 at the free en 9f Specification of Letters Patent.

Patented Decal-3, 1921 1921. Serial No. 472,681

r the seat and this eye or hook 11' is engaged by an eye 12 at the upper end of the prop or supporting leg for the free end of the seat. The said prop comprises "two 'telescopically fitted members, the upper member 13 being preferably a rod of circular cross section having the eye 12formed on its upper extremity and the lower member being preferably a tube 14 which is adapted to have its lower end rest upon the'fioor 15 of the cab and its upper end flared or cupped, as indicated at 16, to facilitate the entrance of the rod 13 into the same and also provide a, seat for'the double springs 17,

fitted around the rod between the said seat" and a stop collar or abutment 18 which is secured upon the rod by a set screw 19, (Midi V the rod may be provided with notches or q sockets 20 to receive the end of the said set. screw so as to more effectuall retain the stop collar in afset position. base member 14 is provided with a plurality of longitudinal slots 21 in its walls and the rod 13 is-providedwith a plurality'of dia-. metrical'openings 22 through which a cotter pin or other stop 23 may be inserted, the

ends of said top playing in alined slots 21 a V of the tubular member.

The lower'end'of'the tubular base member. 14 is free of the floor 15but rests upon the same when the seat is in use, It may, however, be readily lifted slightly from the floor so that the 'leg be swung inwardly he tubular under the seat and the seat then swung pivotally about the rod 3-when it is not to be used so that it will be out of the way and against the wall of the cab. When the seat is in use, as shown in the drawings, the pin 23 is inserted through the registering openings 22 of the rod 13 and the slots 21 of the tube 14 so that the seat will be yieldably supported at the height desired by theuser and the spring 17 will yieldably hold it at such height. The seat may, however, vi-

brate within the limits defined by the slots 21 so that, relative to the cab, the seat will remain in a constant level and the user sup- 1 ported thereon without-fatigue The pin 23 by engaging the upper ends of the slots 21 in which it plays will prevent separation of the members of the prop, and by engaging the lower ends of said slots will limit the downward movement of the seat so that excessive compression of the cushioning springs will be avoided and the user of the seat w' l not be subjected to tiring movements. The stop'collar 18 may be readily adjusted upon the rod 13 and the tension or the cushioning springs thereby varied according to the weight to be placed upon the seat. My improved construction presents a neat appearance and firmly supports the seat while permitting suflicient movement of the same to counteract the vibrations to which a locomotive cab i subjected and thereby relieve the engineman of fatigue. When it is necessary, the eyes 11 and 12 may be readily disengaged and the hooks 8 may be released from the seat-carrying rod 3 so that the seat may be easily removed and brolren springs or other parts consequently readily renewed.

It will be understood, of course, that in practice an auxiliary supporting rod will be provided upon the side Wall of the cab above the seat as set forth in my aforesaid patent.

It will also be understood that bolts are engaged through the ends of the seat-carrying rod and through the bottoms of the hangers and equipped withw ng lock nuts below the hangers in order that excessive vibration may be prevented and "the tension of the springs 4 regulated.

While the seat is intended particularly "for use by locomotive firemen and engineers, it is adapted for use in situations other than locomotive cabs.

Having thus described the invention, What is claimed as new is:

The combination of a seat pivotally mounted at one end upon a fixed support, a supporting legfor the free end of the seat comprising an upper member pivota'lly con nected to the free end or the seat and. depending therefrom and provided with a plurality of diametricopenings in its lower portion, a lower tubular member receiving said upper member and provided with a series of longitudinal slots in its walls, a stop selectively engaging openings in the upper member and selectively engaging slots in the lower member, the slots being of unequal lengthand a cushion interposed between the members.

In testimony whereof I afiiX my signature.
